Abstract

Un appareil de réception comprend : un premier décodeur conçu pour le décodage d'un signal émis par l'intermédiaire d'une première couche provenant d'un signal de multiplexage par répartition en couches à l'aide d'une matrice de vérification de parité afin de générer des bits de mot d'informations de vérification de parité à faible densité et des bits de parité; un codeur conçu pour le codage des bits de mot d'informations de vérification de parité à faible densité, générés par le décodage du signal émis par l'intermédiaire de la première couche, à l'aide de la matrice de vérification de parité afin de générer des bits de parité correspondant uniquement à des colonnes prédéfinies dans la matrice de vérification de parité; et un deuxième décodeur conçu pour le décodage d'un signal obtenu par la suppression, dans le signal de multiplexage par répartition en couches, d'un signal correspondant aux bits de mot informations de vérification de parité à faible densité générés par le décodage du signal émis par l'intermédiaire de la première couche, les bits de parité générés par le codeur et les bits de parité générés par le premier décodeur à l'exception des bits de parité générés par le codeur, ce qui permet de générer des bits de mot d'information émis par l'intermédiaire d'une deuxième couche.
